What is written in this satellite photograph? (Characters identified: 忠于毛主席)

Question

What is written in Chinese at this location 40.449787, 116.548828 on Google maps?

Tried using translators. But didn't find any feasible answer for this.

I used Google translator and wrote these words 于 毛 王 床 and got this translation - Yu Mao king bed.

Answer 1

The characters read:

忠于毛主席
Zhōng yú Máo zhǔxí

• 忠 means faithful;
• 于 is a multi-use preposition which, to me, sounds a bit archaic/formal, and here means "to", but can also mean "in" or "on";
• 毛 is Mao Zedong's surname;
• 主席 means "chairman".

So this translates to "Faithful to Chairman Mao". By the way, if you give the correct characters to Google, the translation it gives is Loyal to Chairman Mao.

Answer 2

This means we are loyal to Chairman Mao.
